INP is already a core metric of the Core Web Vitals


Today, Tuesday, Google started using INP as a new core metric in its Core Web Vitals, replacing FID for good, although it will still be available in the report archive.

INP, in its literal translation, means something like "interaction with the next painting". That is, the time it takes for the user to be able to interact with all the pieces of content after they have been displayed (painted).

As far as I understand, with this new metric, the measurement will no longer be limited to the first painting, which caused many to optimise the first painting (FCP) and neglect or neglect the rest of the page elements up to the footer.

If you are in the optimisation business or simply a WPO lover, you can read a bit about what you need to do now to keep this new metric under control.

So that's the Core Web Vitals:

LCP: Largest Contentful Paint. It measures the performance of the load. To provide a good user experience, the LCP should occur within 2.5 seconds of the page first starting to load.

CLS: Cumulative Layout Shift. Measures visual stability. To provide a good user experience, it should maintain a CLS of 0.1 or less. Related.

INP: Interaction to Next Paint. Measures overall responsiveness to user interactions. Google considers a good user experience if this value is below or within 200 milliseconds.

The measurements offered by are only for the mobile version, to see the results for the desktop version you can go to the traditional PagesSpeed Insight at or consult the complete results offered on this same page which, in addition to being very complete, are broken down and also include the results for tablets and there you have historical data. In my case since August 2022.

To get to the full results, just click on CrUX Dashboard after the analysis.

My metrics are still quite healthy, so I don't have to worry about the INP for the moment, at least on the main pages, although on some long posts there is still room for improvement.

It goes without saying that you shouldn't get too obsessed with these things because to have everything at its best, in green and at 100, you would have to remove a lot of things or lighten the blog elements so much that the site would end up looking like a wasteland.

It is good and advisable to have a page that loads fast, for many reasons, but you can also ruin the user experience if you don't find the right balance and fall into over-optimisation.
